I would say the exact opposite: by default, all zero-length events should happen between the grace music and the restarting of real time (i.e., “after” the grace and “before” the real moment) — so the order would be 0. music before moment M [regular time stops at “the limit of M-minus-m as m approaches zero”] [liminal space begins] 1. zero-length events connected with grace music 2. grace music [liminal space ends] [moment M finally arrives] 3. zero-length events connected with post-grace music 4. post-grace music The only “handwavy” thing I see about my approach is exactly how to code the “connected with” in #1… but given the fact that we have slur ids and the like, I can’t imagine that’s unsolveable.
